King's Quest VI: Heir Today, Gone Tomorrow is a point-and-click adventure game, first released in 1992 as the sixth installment in the King's Quest series produced by Sierra On-Line. Written by Roberta Williams and Jane Jensen, King's Quest VI is widely recognized as the high point in the series for its landmark 3D graphic introduction movie (created by Kronos Digital Entertainment) and professional voice acting (Hollywood actor Robby Benson provided the voice for Prince Alexander, the game's protagonist). King's Quest VI was programmed in Sierra's Creative Interpreter and was the last King's Quest game to be released on floppy disk. A CD-ROM version of the game was released in 1993, including more character voices, a slightly different opening movie and more detailed artwork and animation.
The name of this sequel is a pun on the common phrase "here today, gone tomorrow". This pun is related to the abrupt departure of Prince Alexander after the events of King's Quest V, where he was just rescued by King Graham along with Princess Cassima, who asked Alexander to come visit her at the end of that game. King's Quest III: To Heir Is Human also contained the word "heir" in its title and also featured Prince Alexander (then known as the slave Gwydion) as the main character.
Gameplay
King's Quest VI is a 2D graphic adventure game with a point-and-click interface. The player is given an icon-based toolbar at the top of the screen of selectable functions: walk, look (provides a description from the narrator of the object targeted), action and talk, respectively. It also includes the item inventory (the last selected item can be picked right away) and a game options menu. This is the second game in the series to feature this interface, which was introduced in its immediate predecessor King's Quest V as a new feature of the SCI1 version of Sierra's Creative Interpreter engine; previous titles in the series featured a text parser where players had to type commands and actions instead of selecting them on the screen.
Gameplay involves solving puzzles. Those include logic puzzles and interacting with characters either by dialogue or usage of collected items. One of the puzzles requires consulting the booklet "Guidebook to the Land of the Green Isles", which is included in the game's package. Aside from providing additional background to the game's setting, this booklet serves as part of the game's copy-protection. The player will not be able to pass the puzzles on the Cliffs of Logic that guard the Isle of the Sacred Mountain without information from the booklet. The booklet also includes a poem encoding the solution to one of the puzzles in the labyrinth on the island. In the re-released edition, the guide is part of the manual released on the game CD.
Solving the puzzles in the game usually requires traveling between the islands that make up the game world, which is accomplished by means of a magic map. Although a magic map had been used in earlier games of the series such as King's Quest III, its implementation in King's Quest VI was different from earlier games in that it was only used for travel between islands, which could not be reached using the walking interface.
Plot
The game takes place almost entirely in a fictional kingdom called the Land of the Green Isles. The kingdom comprises several islands, and is described as being largely isolated from the outside world. The player can travel between different islands after obtaining a magic map.
The center of the kingdom is the Isle of the Crown, which has an Arabian Nights theme. The Isle of Wonder is inspired by Alice in Wonderland, and the Isle of the Sacred Mountain is inspired by Classical mythology. The Isle of the Beast, inspired by Beauty And The Beast, is heavily forested and scattered with magical barriers. There also are additional hidden areas. One of these is inhabited by a tribe of druids, while another gives the player the option to confront Death.
The game's opening cutscene shows Prince Alexander haunted by his memories of Princess Cassima, who he met at the end of King's Quest V when they were both rescued from the wizard Mordack. After seeing a vision of Cassima in the magical mirror that his father acquired in the first King's Quest, he sails to find her. At the beginning of the game he is shipwrecked on the shore of the Isle of the Crown, where he learns that the vizier Abdul Alhazred (named after the author of the fictional Necronomicon) has assumed control in Cassima's absence, and plans to force her to marry him. Alexander must explore the Land of the Green Isles in order to find and learn what he needs to rescue Cassima from the vizier.
Multiple endings
A significant aspect of KQ6's story and gameplay is the option for the player to receive different endings based on choices made during the course of the game. Partway through the game, the player has the option to pursue either the "short path", which finishes the game rather quickly, or the "long path", which contains more puzzles and leads to a more satisfying ending. Upon completing either path, the player is given a clue about what choices would have led to the other ending. In addition to the two main paths and endings, the game's endings also contain many minor variables based on optional tasks in the game that the player may or may not have performed. Almost half of the game's quests are optional, many have multiple solutions, and because of the game's open world design players can solve most in any order.
